Abstract
Diabetic neuropathy is one of the most common diabetes mellitus complications associated with mediocalcinosis of the lower extremities, a significant decrease in feet bone mineral density, and a high incidence of cardiovascular disease. In most cases, calcium-phosphorus metabolism changes occur in patients with diabetic neuroarthropathy, or Charcot foot, when we can observe feet local osteoporosis, which in 90% of cases associated with a vessel's calcification of the lower extremities in the majority of diabetes population. A large number of studies presented literature have demonstrated that patients with Charcot foot can have accelerated bone metabolism and increased bone resorption. Patients with Charcot foot often have crucial abnormalities in the calcium-phosphorus parameters, bone metabolism, and levels of vitamin D and its metabolites. In addition, the duration of diabetes mellitus, the degree of its compensation widely affects the development of its micro- and macrovascular complications, which could also accelerate the development of mineral and bone disorders in these types of patients. Multifactorial pathogenesis of these disorders complicates the management of patients with a long and complicated course of diabetes mellitus. This review discusses the peculiarities of vitamin D metabolism, the importance of timely diagnosis in phosphorus-calcium disorders, and the specifics of therapy in these patients. Special attention is paid to the timely diagnosis of the Charcot's foots acute stage based on the bone marrow edema by MRI evaluation and the possibility of reducing the immobilization period.

Abstract
The differentiation between acute Charcot neuroarthropathy and infection in the foot and ankle should be supported by multiple criteria. A detailed history and physical examination should always be completed. Plain radiographs should be performed, though advanced imaging, currently MRI, is more helpful in diagnosis. Scintigraphy and PET may become the standard imaging modalities once they are more clinically available due to their reported increased accuracy. Laboratory analysis can also act as a helpful diagnostic tool. Histopathology with culturing should be performed if osteomyelitis is suspected. The prompt diagnosis and initiation of treatment is vital to reducing patient morbidity and mortality.

[PMID: 36692512 PMCID: PMC10344513 DOI: 10.1097/corr.0000000000002546] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/29/2022] [Accepted: 12/15/2022] [Indexed: 01/25/2023]
Abstract
BACKGROUND The cause of Charcot neuro-osteoarthropathy (CN) is diabetes in approximately 75% of patients. Most reports on the clinical course and complications of CN focus on diabetic CN, and reports on nondiabetic CN are scarce. No study, to our knowledge, has compared the clinical course of patients initially treated nonoperatively for diabetic and nondiabetic CN. QUESTIONS/PURPOSES Among patients with CN, are there differences between patients with diabetes and those without in terms of (1) the frequency of major amputation as ascertained by a competing risks survivorship estimator; (2) the frequency of surgery as ascertained by a competing risks survivorship estimator; (3) frequency of reactivation, as above; or (4) other complications (contralateral CN development or ulcers)? METHODS Between January 1, 2006, and December 31, 2018, we treated 199 patients for diabetic CN. Eleven percent (22 of 199) were lost before the minimum study follow-up of 2 years or had incomplete datasets and could not be analyzed, and another 9% (18 of 199) were excluded for other prespecified reasons, leaving 80% (159 of 199) for analysis in this retrospective study at a mean follow-up duration since diagnosis of 6 ± 4 years. During that period, we also treated 78 patients for nondiabetic Charcot arthropathy. Eighteen percent (14 of 78) were lost before the minimum study follow-up and another 5% (four of 78 patients) were excluded for other prespecified reasons, leaving 77% (60 of 78) of patients for analysis here at a mean of 5 ± 3 years. Patients with diabetic CN were younger (59 ± 11 years versus 68 ± 11 years; p < 0.01), more likely to smoke cigarettes (37% [59 of 159] versus 20% [12 of 60]; p = 0.02), and had longer follow-up (6 ± 4 years versus 5 ± 3 years; p = 0.02) than those with nondiabetic CN. Gender, BMI, overall renal failure, dialysis, and presence of peripheral arterial disease did not differ between the groups. Age difference and length of follow-up were not considered disqualifying problems because of the later onset of idiopathic neuropathy and longer available patient follow-up in patients with diabetes, because our program adheres to the follow-up recommendations suggested by the International Working Group on the Diabetic Foot. Treatment was the same in both groups and included serial total-contact casting and restricted weightbearing until CN had resolved. Then, patients subsequently transitioned to orthopaedic footwear. CN reactivation was defined as clinical signs of the recurrence of CN activity and confirmation on MRI. Group-specific risks of the frequencies of major amputation, surgery, and CN reactivation were calculated, accounting for competing events. Group comparisons and confounder analyses were conducted on these data with a Cox regression analysis. Other complications (contralateral CN development and ulcers) are described descriptively to avoid pooling of complications with varying severity, which could be misleading. RESULTS The risk of major amputation (defined as an above-ankle amputation), estimated using a competing risks survivorship estimator, was not different between the diabetic CN group and nondiabetic CN group at 10 years (8.8% [95% confidence interval 4.2% to 15%] versus 6.9% [95% CI 0.9% to 22%]; p = 0.4) after controlling for potentially confounding variables such as smoking and peripheral artery disease. The risk of any surgery was no different between the groups as estimated by the survivorship function at 10 years (53% [95% CI 42% to 63%] versus 58% [95% CI 23% to 82%]; p = 0.3), with smoking (hazard ratio 2.4 [95% CI 1.6 to 3.6]) and peripheral artery disease (HR 2.2 [95% CI 1.4 to 3.4]) being associated with diabetic CN. Likewise, there was no between-group difference in CN reactivation at 10 years (16% [95% CI 9% to 23%] versus 11% [95% CI 4.5% to 22%]; p = 0.7) after controlling for potentially confounding variables such as smoking and peripheral artery disease. Contralateral CN occurred in 17% (27 of 159) of patients in the diabetic group and in 10% (six of 60) of those in the nondiabetic group. Ulcers occurred in 74% (117 of 159) of patients in the diabetic group and in 65% (39 of 60) of those in the nondiabetic group. CONCLUSION Irrespective of whether the etiology of CN is diabetic or nondiabetic, our results suggest that orthopaedic surgeons should use similar nonsurgical treatments, with total-contact casting until CN activity has resolved, and then proceed with orthopaedic footwear. A high frequency of foot ulcers must be anticipated and addressed as part of the treatment approach. LEVEL OF EVIDENCE Level III, prognostic study.

Abstract
The National Institute of Health now estimates that there are well over 37 million persons with diabetes in the United States alone, a number well over 11 per cent of our population. The associated multiple organ system disease is responsible for more than 327 billion dollars in direct and indirect medical costs and more than 140,000 lower extremity amputations yearly in the United States. Because healthcare professionals have begun to appreciate the economic and pathologic burden that diabetes imparts on our society, there has been a growth in both the understanding and treatment of the responsible pathologic disorders. The goal of this monograph is to provide an evidence-supported foundation to better understand the pathophysiology that leads to the development of neuropathic (Charcot) foot arthropathy and provide insight into developing a treatment plan for addressing this complex disease process that presents in a highly comorbid patient population.

Abstract
BACKGROUND Charcot arthropathy (CN) can ultimately lead to limb loss despite appropriate treatment. Initial conservative treatment is the accepted treatment in case of a plantigrade foot. The aim of this retrospective study was to investigate the mid- to long-term clinical course of CN initially being treated conservatively, and to identify risk factors for reactivation and contralateral development of CN as well as common complications in CN. METHODS A total of 184 Charcot feet in 159 patients (median age 60.0 (interquartile range (IQR) 15.5) years, 49 (30.1%) women) were retrospectively analyzed by patient chart review. Rates of limb salvage, reactivation, contralateral development and common complications were recorded. Statistical analysis was performed to identify possible risk factors for limb loss, CN reactivation, contralateral CN development, and ulcer development. RESULTS Major amputation-free survival could be achieved in 92.9% feet after a median follow-up of 5.2 (IQR 4.25, range 2.2-11.25) years. CN recurrence occurred in 13.6%. 32.1% had bilateral CN involvement. Ulcers were present in 72.3%. 88.1% patients were ambulating in orthopaedic footwear without any further aids. Presence of Diabetes mellitus was associated with reactivation of CN, major amputation and ulcer recurrence. Smoking was associated with ulcer development and necessity of amputations. CONCLUSIONS With consistent conservative treatment of CN with orthopaedic footwear or orthoses, limb preservation can be achieved in 92.9% after a median follow-up of 5.2 years. Patients with diabetic CN are at an increased risk of developing complications and CN reactivation. To prevent ulcers and amputations, every effort should be made to make patients stop smoking.

Abstract
There are many similarities between nondiabetic and diabetic Charcot neuroarthropathy (CN) but many of the underlying causes causing nondiabetic neuropathy and CN are associated with poor bone quality. Patient workup for nondiabetic CN should include the underlying cause of the neuropathy and optimization of bony healing, such as vitamin D supplementation and bisphosphonate or calcitonin administration. Surgical reconstruction should include the most robust fixation possible, as nondiabetic patients with CN are more prone to delayed union.

Abstract
Surgical intervention for Charcot arthropathy is becoming more common; this is driven by an increased prevalence, better understanding of the cause, identifying patient risk factors that influence outcomes, and how to best optimize these. This article aims to summarize the cause of Charcot, look at the factors that influence the outcomes, and the financial cost of managing what is a very challenging condition.

Abstract
Conservative treatment of Charcot neuro-osteoarthropathy (CN) aims to retain a stable, plantigrade, and ulcer-free foot, or to prevent progression of an already existing deformity. CN is treated with offloading in a total contact cast as long as CN activity is present. Transition to inactive CN is monitored by the resolution of clinical activity signs and by resolution of bony edema in MRI. Fitting of orthopedic depth insoles, orthopedic shoes, or ankle-foot orthosis should follow immediately after offloading has ended to prevent CN reactivation or ulcer development.

Abstract
The primary aim of this study is to compare the preoperative risk factors and postoperative outcomes between Charcot neuroarthropathy patients with dislocation versus purely fracture pattern breakdown. The secondary aim is to compare the same factors between Charcot neuroarthropathy patients with dislocation versus fracture-dislocation pattern breakdown. A total of 55 patients with forefoot, midfoot, or hindfoot Charcot Neuroarthopathy were assessed at a mean follow up of 2.99 years. Bivariate analysis compared preoperative risk factors and postoperative outcomes, and segmented multivariable regression analysis was performed. Dislocation pattern Charcot had statistically significant higher rates of broken hardware (p = .05), mean age (p = .01), and revisional exostectomy (p = .01) compared to pure fracture pattern Charcot. Dislocation pattern Charcot was 12 times more likely to have revisions exostectomy (odds ratio [OR] 12.0, 95% confidence interval [CI] 1.84-78.37), and was 8 times more likely to have osteomyelitis (OR 7.8, 95% CI 1.4-42.7, p = .02) compared to the fracture-dislocation pattern Charcot. The patients with pure fracture pattern Charcot were 58.8 times more likely to have Charcot breakdown involvement of the talonavicular joint compared to the dislocation pattern cohort (OR 58.83, 95% CI 1.1-3220.3). Involvement of the talonavicular joint, in the fracture pattern Charcot associate with medial column collapse occurring at the onset of Charcot breakdown. The dislocation pattern in Charcot Neuroarthropathy demonstrated a higher propensity for residual collapse as demonstrated by the higher rates of broken hardware, osteomyelitis, and need for revisional exostectomy.

Abstract
The objective of this study is to compare risk adjusted matched cohorts of Charcot neuroarthropathy patients who underwent osseous reconstruction with and without diabetes. The 2 groups were matched based on age, body mass index, hypertension, history of end-stage renal disease, and peripheral arterial disease. Bivariate analysis was performed for preoperative infection, location of Charcot breakdown, and post reconstruction outcomes, in patients with a minimum of 1 year follow-up period. Through bivariate analysis, presence of preoperative ulceration (p = .0499) was found to be statistically more likely in the patients with diabetes; whereas, delayed osseous union (p = .0050) and return to ambulation (p ≤ .0001) was statistically more likely in patients without diabetes. The nondiabetic Charcot patients were 17.6 folds more likely to return to ambulation (odds ratio [OR] 17.6 [95% confidence interval {CI} {3.5-87.6}]), and 16.4 folds more likely to have delayed union (OR 16.4 [95% CI {1.9-139.6)]). Subanalysis compared well-controlled diabetic and nondiabetic Charcot neuroarthropathy patients for same factors. Multivariate analysis, in the subanalysis, found return to ambulation was 15.1 times likely to occur in the nondiabetic CN cohort (OR 15.1 [95% CI 1.3-175.8]) compared to the well-controlled diabetic CN cohort.

Abstract
BACKGROUND The contralateral foot in Charcot arthropathy or neuroarthropathy (CN) is subject to increased plantar pressure. To date, the clinical consequences of this pressure elevation are yet to be determined. The aim of this study was to evaluate ulcer and amputation rates of the contralateral foot in CN. METHODS We abstracted the medical records of 130 consecutive subjects with unilateral CN. Rates of contralateral CN development and recurrence, contralateral ulcer development, and contralateral amputations were recorded. Statistical analysis was performed to identify possible risk factors for contralateral CN and ulcer development, and contralateral amputation. Mean follow-up was 6.2 (SD 4) years. RESULTS After a mean of 2.5 years, 19.2% patients developed contralateral CN. Female gender was associated with contralateral CN development (odds ratio 3.13, 95% confidence interval 1.27, 7.7). Overall, 46.2% patients developed a contralateral ulcer. Among the patients who developed contralateral CN, 60% developed an ulcer. Sanders type 2 at the index foot (midfoot CN) was significantly associated with contralateral ulcer development. Ulcer-free survival (UFS) differed significantly between patients with diabetes type 1 (median UFS 5131 days) and patients with diabetes type 2 (median UFS 2158 days). A total of 25 amputations had to be performed in 22 (16.9%) patients. Three of those 22 patients (2.3%) needed major amputation. CONCLUSION Almost 20% of patients developed contralateral CN. Nearly half of people with CN developed a contralateral foot ulceration. Patients with type 2 diabetes had significantly shorter UFS than patients with diabetes type 1. Every sixth patient needed an amputation, with the majority being minor amputations. The contralateral foot should be monitored closely and included in the treatment in patients with CN.

Abstract
OBJECTIVE A wide range of clinical presentations of Charcot neuroarthropathy of the foot with concomitant osteomyelitis in patients with diabetes has been described. Existing literature provides an equally diverse list of treatment options. The purpose of this systematic review was to assess the outcomes specifically for the surgical management of midfoot Charcot neuroarthropathy with osteomyelitis in patients with diabetes. METHOD A systematic review was conducted by three independent reviewers using the following databases and search engines: Cumulative Index of Nursing and Allied Health Literature (CINAHL), Cochrane Library, EMBASE (Excerpta Medica dataBASE), Google Scholar, Ovid, PubMed and Scopus. Search terms used were: Charcot neuroarthropathy, osteoarthropathy, neuro-osteoarthropathy, neurogenic arthropathy, osteomyelitis, midfoot, foot, ankle, diabetes mellitus, ulceration, wound, infection, surgical offloading, diabetic reconstruction, internal fixation, external fixation. Studies meeting the following criteria were included: English language studies, studies published from 1997-2017, patients with diabetes mellitus surgically treated for Charcot neuroarthropathy of the midfoot (specified location) with concomitant osteomyelitis, with or without internal and/or external fixation, follow-up period of six months or more postoperatively, documentation of healing rates, complications, and need for revisional surgery. Studies which were entirely literature reviews, descriptions of surgical-only technique and/or cadaveric studies, patients without diabetes, studies that did not specify location of osteomyelitis and Charcot neuroarthropathy, and treatment proximal to and including Chopart's/midtarsal joint specifically talonavicular, calcaneocuboid, subtalar, ankle were excluded. RESULTS A total of 13 selected studies, with a total of 114 patients with diabetes of which 56 had surgical treatment for midfoot Charcot neuroarthropathy with osteomyelitis, met the above inclusion criteria and were used for data extraction. CONCLUSION Surgical intervention for midfoot Charcot neuroarthropathy with osteomyelitis in patients with diabetes demonstrated a relatively high success rate for a range of procedures including debridement with simple exostectomy, arthrodesis with or without internal or external fixation, and advanced soft tissue reconstruction. However, this systematic review emphasises the need for larger, better designed studies to investigate the efficacy and failure rates of surgical treatment in this group of patients.

Abstract
Understanding new theories of the epidemiology of Charcot neuroarthropathy is practice changing. Treatment of Charcot neuroarthropathy is evolving from a passive approach to one that sees the urgency of proactive, early recognition, thereby avoiding the cascading events that lead to the complex, limb-threatening deformities. Preventive medicine is the most efficient at avoiding severe deformity, with prolonged offloading and immobilization as the current mainstay of treatment. However, with recent advancements in medical and surgical modalities, this may become the treatment of the past as clinicians begin to favor medical management and early surgical intervention.

Abstract
Charcot arthropathy is an infrequent condition that primarily involves the foot and ankle; rarely, it has been reported to affect the knee. Risk factors for Charcot arthropathy are well described with diabetes being the most common cause. Idiopathic Charcot arthropathy without a secondary etiology is extremely rare, with only a few cases described involving the foot and shoulder. Clinically, idiopathic Charcot arthropathy presents a notable challenge because delayed diagnosis can lead to surgical complications and advancement of joint destruction. We report idiopathic Charcot arthropathy of the knee presenting as a bicondylar tibial plateau fracture successfully managed with total knee arthroplasty after failed open reduction internal fixation. We diagnosed the patient when the clinical/surgical presentation was indicative of Charcot arthropathy and after excluding all other diagnoses. This previously unreported case describes the complexity of idiopathic Charcot arthropathy with subsequent fractures and highlights the importance of patient history, presentation, and surgical intervention.

Abstract
Charcot foot is a rare but severe, and possibly limb-threatening, complication to neuropathy and diabetes mellitus. The current treatment consists of long-term off-loading, and has a large negative impact on the patient's life. Much research has gone into understanding the condition and its biochemical mechanisms, however, the underlying pathogenesis of a Charcot foot is not yet fully understood. In the recent decades several key advances in our understanding of the Charcot foot have been made, both in regards to the changes in bone metabolism and structure an acute Charcot foot can cause, and to the molecular pathways involved in this. This review summerizes the available research into the bone metabolism around a Charcot foot, with an emphasis on the biochemical profile. The existing data regarding attempts at medical treatment is also reviewed, including novel trials targetting specific inflammatory pathways upregulated in the acute diabetic Charcot foot.

Abstract
INTRODUCTION We evaluated the radiographic outcomes and surgical costs of surgically treated rotational ankle fractures in our health system between providers who had completed a trauma fellowship and those who had not. METHODS We grouped patients into those treated by trauma-trained orthopaedic surgeons (TTOS) and non-trauma-trained orthopaedic surgeons (NTTOS). We graded the quality of fracture reductions and calculated implant-related costs of treatment. RESULTS A total of 208 fractures met the inclusion criteria, with 119 in the TTOS group and 89 in the NTTOS group. Five patients lost reduction during the follow-up period. The adequacy of fracture reduction at final follow-up did not differ (P = 0.29). The median surgical cost was $2,940 for the NTTOS group and $1,233 for the TTOS group (P < 0.001). DISCUSSION We found no notable differences in radiographic outcomes between the TTOS and NTTOS groups. Cost analysis demonstrated markedly higher implant-related costs for the NTTOS group, with the median surgical cost being more than twice that for the TTOS group. LEVEL OF EVIDENCE Level III.

Abstract
OBJECTIVE Due to the localized nature of Charcot foot, systemically altered levels of inflammation markers can be difficult to measure. The aim of this study was to investigate whether it is possible to detect an arteriovenous (A-V) flux in any locally produced inflammatory biomarkers from an acute Charcot foot by comparing local and systemic measurements. METHODS We included patients with acute diabetic Charcot foot. Blood was sampled from the vena saphena magna on the distal part of the crus bilaterally as well as from the arteria radialis. To minimize the A-V shunting effect, the feet were externally cooled with ice water prior to resampling. RESULTS Both before and after cooling, the A-V flux of interleukin-6 (IL-6) between the Charcot feet and the arterial level was significantly higher than the flux between the healthy feet and the arterial level (Δvaluebefore: 7.25 versus 0.41 pg/mL, resp., p = 0.008; Δvalueafter: 10.04 versus 1.68 pg/mL, resp., p = 0.032). There were no differences in the fluxes for other markers of inflammation. CONCLUSION We have found an increased A-V flux of IL-6 in the acute diabetic Charcot foot compared to the healthy foot in the same patients.

Abstract
BACKGROUND Arthrodesis is a common operative procedure used to manage arthritis and deformity in the foot and ankle. Nonunion is a possible and undesirable outcome in any arthrodesis surgery. Rates of nonunion in the foot and ankle literature range from 0% to 47% depending on the patient population and joint involved. Multiple factors can contribute to developing a nonunion including location, fixation method, tobacco use, diabetes, infection, and others. METHODS The case logs of 3 foot and ankle surgeons were reviewed from January 2007 to September 2014 to identify nonunion arthrodesis revision cases. The patient factors reviewed included diabetes, inflammatory arthropathy, tobacco use, history of infection, nonunion elsewhere, neuropathy, Charcot arthropathy, posttraumatic arthritis, and prior attempt at revision arthrodesis at the same site. Operative records were reviewed to identify location of the nonunion, instrumention, use of allograft or autograft bone, use of iliac crest bone marrow aspirate (ICBMA) and use of orthobiologics such as bone morphogenetic protein (BMP) during the revision arthrodesis. Successful revision was defined as radiographic union on the final radiograph during follow-up. Eighty-two cases of revision arthrodesis were identified with an average follow-up of 16 months. RESULTS The overall nonunion rate was 23%. Neuropathy and prior attempts at revision were identified as significant risks (P <.05) for persistent nonunion. Odds ratio calculated based on previous attempts at revision arthrodesis found a 2.8-fold increase in the risk of failure for each attempt at revision. CONCLUSION Revision arthrodesis for nonunion in the foot and ankle was successful (77%) under a variety of patient and operative conditions. Neuropathy was a significant patient risk factor for persistent nonunions, and we believe it is important to identify even in the nondiabetic patient. As the number of attempts at revisions increases, there is a subsequent 3-fold increase in the risk of persistent nonunion. LEVEL OF EVIDENCE Level IV, case series.

Abstract
BACKGROUND The foot and ankle surgeon can see peripheral neuropathy in the treatment of foot and ankle conditions. The purpose of this study was (1) to evaluate the demographics and presenting complaints of patients diagnosed with idiopathic peripheral neuropathy during an examination by a foot and ankle surgeon and (2) to identify the type and frequency of subsequent diagnosis of medical causes of neuropathy. METHODS This was a retrospective study of patients diagnosed with idiopathic peripheral neuropathy in our practice between January 1997 and December 2008. Ninety-five patients were identified, and demographic data, presenting complaints, and medical comorbidities were extracted from the medical record. Examination findings of decreased sensation to Semmes Weinstein 5.07 monofilament testing were documented, and electromyogram and nerve conduction study results were reviewed when available. Laboratory values were noted, as were neurologic evaluations performed to diagnose medical conditions associated with peripheral neuropathy. RESULTS The most common presentation was foot pain, in 36 patients (38%). Ninety-one patients had Semmes Weinstein 5.07 monofilament testing, with loss of protective sensation reported in 75 of the 91 tested (82%). Only 30 of the 95 patients had electromyogram and nerve conduction study results available, with a test positive for peripheral neuropathy in 20 of the 30 tested. Thirty-two patients were evaluated by a neurologist. A specific cause was identified in 12 of the 32 seen by a neurologist. Of the total group of 95 patients, 31 patients (33%) were diagnosed with a condition that may be associated with peripheral neuropathy. CONCLUSIONS Thirty-three percent of the patients presenting to our clinic and given a diagnosis of idiopathic peripheral neuropathy were ultimately diagnosed with a medical cause of neuropathy-most commonly, diabetes. For those patients with idiopathic neuropathy, a spectrum of disease was encountered, including pain, ulcer, infection, and Charcot neuroarthropathy.

Abstract
Charcot foot syndrome is an uncommon complication of diabetes but is potentially devastating in its consequences. Outcome is made worse by widespread professional ignorance leading to delayed diagnosis, but it is also hampered by lack of understanding of its causes and lack of treatments with proven effectiveness, other than offloading. There remains a desperate need for studies into its causes as well as comparative audit and trials designed to determine the best treatment for this difficult condition. Such work can probably only be effectively carried out through the establishment of multicentre networks. Nevertheless, improved understanding in recent years of the likely role of inflammatory pathways has raised awareness of the multiple ways in which the effects of neuropathy may be manifest in the development of the Charcot foot. This awareness is also leading to the realization that similar processes may conceivably contribute to the refractoriness of other foot diseases in diabetes, including both chronic unhealing ulcers and osteomyelitis.

Clinical benefit and improvement of activity level after reconstruction surgery of Charcot feet using external fixation: 24-months results of 292 feet. BMC Musculoskelet Disord 2014; 15:392. [PMID: 25417055 PMCID: PMC4289265 DOI: 10.1186/1471-2474-15-392] [Citation(s) in RCA: 16] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/14/2014] [Accepted: 11/11/2014] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Reconstruction of Charcot feet remains a surgical challenge. The goal of this study was to investigate safety and clinical benefit from reconstruction of Charcot feet using an external fixator. There is limited valid data regarding long-term outcomes for Charcot foot procedures. METHODS In a retrospective study, 292 Charcot feet (282 patients) undergoing reconstructive procedures in our clinic from 1996-2010 were included (93 female, 189 male, mean age 57.9 years). Average follow-up was 24.1 months. Exclusion criteria were previous major amputation on the same side. All patients underwent surgery using a Hoffmann II external fixator for six to eight weeks with offloading. The fixator was then removed, and a customized AFO with full weight bearing was applied for another 11 months. After one year, patients received customized orthopedic shoes. RESULTS Initial amputations were avoided. Patient activity improved significantly by more than 1 level (SD 0.67, p < .001) according to the Hoffer activity score for lower limb amputees. The most common minor complication was persistent or recurrent ulceration in 67 feet (23%). Secondary amputation (after failure of external fixation) was required in only 12 patients (6.2%). Orthopedic shoes were used by approximately 34% of patients 18 months after surgery. CONCLUSIONS Reconstructive surgery of Charcot feet using external fixation is a safe and economically feasible procedure. Activity levels improved significantly by more than 1 level (p < 0.01), severe complications were rare, and secondary amputation was required in only 12 patients (6.2%) of a high-risk patient population. Use of an external fixator offers the advantage that all extraneous material is removed after six weeks; thus, there is no risk of broken screws or plates and the associated potential complications.
